Low Profile 4 Mbit/s (FIR) Infrared Transceiver Module with
independent Logic Supply Voltage
DescriptionThe Vishay TFBS6614 is the lowest profile (2.7 mm)
4 Mbit/s Infrared Data Transceiver module available.
A photo PIN diode, an infrared emitter (IRED) and a
low-power CMOS control IC are integrated in a single
package that provides a total front-end solution.
VLOGIC - allows a low-voltage controller to connect
directly to TxD, RxD and SD/Mode logic signals of the
transceiver hence eliminating the need for costly sig-
nal level converter and reducing power consumption.
The TxD-echo function is enabled for internal self-
test. During transmission the TxD signals are echoed
at RxD output to perform the internal self-test.
The Shut Down (SD) feature cuts current consump-
tion to less than 10 nA.
Features Smallest FIR Transceiver available:
